n.
A telescope in which light from the object is gathered and focused by a concave mirror, with the resulting image magnified by the eyepiece.

adj.
2. consisting of parts that slide one within another.
v.t.
3. to force together, one into another, in the manner of the sliding tubes of a jointed telescope.
4. to shorten or condense.
v.i.
5. to slide together in the manner of the tubes of a telescope.
